VENTILATING-CANOPY.

Specification of Letters Patent.

Patented Oct. 11, 1910.

Application filed January 12, 1910. Serial No. 537,693.

To all whom it may concern:

Be it known that I, JAMES N. MooDY, a citizen of the United States, residing at South Boston, in the county of Halifax and State of Virginia, have invented certain new and useful Improvements in Ventilating- Canopies, of which the following is a specification.

This invention relates to canopies for beds, particularly adapted for use in the fresh air treatment of tuberculosis and other lung diseases, and contemplates an improvement over my previous patents for like structures, particularly my latest Patent Number 941685, dated November 30, 1909.

In my present invention, I utilize a detachable canopy and a permanent frame to which the canopy is attached, so constructed that the upper window sash may be lowcred, and the lower one raised, giving free ingress and egress and circulation of air through the canopy to the exclusion of the room.

In the drawing Figure 1 is a perspective view of a window in which the permanent frame is secured, and a bed over which the canopy, which is attached to the frame, is located. Fig. 2 is a vertical section through the window, permanent frame, canopy and head portion of the bed. Fig. 8 is a detail section through a portion of the permanent frame illustrating one of its securing clips, and, Fig. 4 is a similar view through another portion thereof, illustrating one of the canopy attaching hooks.

Referring now, to these figures, 6 indicates a canopy adapted to inclose the head of the bed which, in its details, may be similar to that shown in any of my previous patents, or otherwise constructed to envelop the head of a sleeper upon the bed. This canopy is attached to a frame 7, the size of which is unimportant except that it may be adjustable with respect to width and height, to fit into the lower portion of any window casing and properly support the canopy. Previous to the insertion of frame 7 in place, a permanent frame 8, which may be adjustable with respect to width and height as frame 7 disclosed in my prior patents, is secured in the upper portion of the windows upon the inside of its sash by means of clips and screws 9, the structure of which is shown in Fig. 3, these clips being located upon its upper and side edges. This frame may take the place of the ordinary inside shade and is covered with a light transparent material 8*, for instance celluloid, edged with a fabric 8 which fabric is secured about said frame 8 and may be extended when the frame is enlarged to fit large windows. This frame also has upon its lower edge U-shaped hooks 10 by which the upper edge of the canopy frame 7 is removably attached thereto.

In use, the permanent frame 8 is secured in position within the upper portion of the window and the canopy will be set in place within the lower portion of the window, both as stated and shown, and the upper sash lowered and the lower sash raised as far as desirable. This will give a passage below the lower sash for air to come in and a passage at the upper end of the upper sash for it to go out, creating a free circulation of air within the canopy about the sleepers head, to the exclusion of the room.

The device is protected in stormy weather by hoods or shields 11 secured to, and inclined outwardly and downwardly from, the upper portion of the window frame and the lower portion of the lower sash.

I claim:

1. The combination with a window having upper and lower sashes, of a canopy adapted to fit over the head of. a bed placed adjacent to the window, and a covered frame extending between the upper edge of the canopy and the upper end of the window frame, whereby both the sashes may be opened to permit of free circulation of air through the canopy.

2. The combination with a window having upper and lower sashes, of a covered frame permanently secured within the upper portion of the window, a canopy adapted to fit over the head of a bed placed adjacent the window and having a frame fitting within the lower portion of the window, and means carried by the lower edge of the permanent frame to removably hold the upper edge of the canopy frame thereto.

3. A canopy of the character described comprising a covered frame having securing clips upon its upper and side edges, and attaehing hooks upon its lower edge, a sec ond frame adapted to be engaged with said hooks, and a hood fastened to said last named frame and projecting to one side thereof to inclose the head of a bed, said WVitnesses:

frames being adjustable to fit Within a Win- J. M. EAST, dow casing. J. L. CRAWLEY.

In testimony whereof I afiix my signature in presence of two witnesses.
